我希望复选框有多个值。我该怎么做？它只添加了选择的第一个选项
<input type="checkbox" name="fields[options]" value="option1[]">option1
<input type="checkbox" name="fields[options]" value="option2[]">option2
<input type="checkbox" name="fields[options]" value="option3[]">option3
有两个PHP文件。我会把它们贴在下面。我对php没有那么多经验。
/**************** GOOGLE.DOCS method ************************/
if($_SETTINGS['store_to_gdocs'])
{
include_once("GoogleSpreadsheet/Google_Spreadsheet.php");
$ss = new Google_Spreadsheet($_SETTINGS['gdocs']['user'],$_SETTINGS['gdocs']['password']);
$ss->useSpreadsheet($_SETTINGS['gdocs']['spreadsheet_name']);
$ss->useWorksheet($_SETTINGS['gdocs']['worksheet_name']);
$row = array
(
"Date" => date("m/d/Y H:i"),
);
foreach($_POST['fields'] as $k=>$v)
$row[$k]=$v;
if(!$ss->addRow($row))
$ret['error']=1;
}

谢谢你的帮助！
您的复选框名称和值混淆了。应该是：
<input type="checkbox" name="fields[options][]" value="option1">option1
<input type="checkbox" name="fields[options][]" value="option2">option2
<input type="checkbox" name="fields[options][]" value="option3">option3
现在您可以像这样操作$_POST['fields']['options']：
$options = (is_array($_POST['fields']['options'])) ? $_POST['fields']['options'] : array();
然后你可以内爆它们：
$options_string = implode(',', $options) // will return option1,option2,option3 etc
或者循环通过它们：
foreach ($options as $option)
{
echo $option.'<br>';
}
// produces option1<br>option2<br>option3 etc
不要在数组中为名称指定键，应该将其设置为name="fields[]"。
